Backend Development with Node.js
Node.js is our platform of choice for developing high-performance backend systems and APIs. We create RESTful and GraphQL APIs with Express, Fastify, and Next.js API Routes.
Areas of expertise
- Express
- Fastify
- Socket.io
- Worker Threads
- Streams
- Clustering
Use cases
RESTful API layer
REST APIs with Express or Fastify that serve mobile/web apps — authentication, authorization and OpenAPI doc generation included.
Real-time applications
WebSocket-based systems with Socket.io for chat, live notifications, real-time collaboration or live dashboards.
Background job processor
Queue-based systems (BullMQ, Agenda) for email sending, PDF generation, scheduled reporting and other async tasks.
Microservices and API gateway
A gateway layer in front of multiple small services covering inter-service communication, rate limiting and observability.
Frequently asked questions
Express or Fastify — which is better?
If your team already knows Express, stick with it. For new projects where performance matters, Fastify wins. Fastify is faster and TypeScript-friendly; Express has a larger ecosystem.
Is TypeScript mandatory?
In our projects, yes — it's the standard. Type safety meaningfully reduces refactor cost on large backends; TS support in Mongoose, Express and Fastify is mature.
When to use Cluster or Worker Threads?
CPU-heavy tasks (image processing, crypto, large JSON parsing) → Worker Threads. To use all CPU cores → Cluster mode, or orchestration via PM2/Kubernetes.
Which database pairs best with Node.js?
MongoDB (Mongoose), PostgreSQL (Prisma/Drizzle), Redis (cache + queue) — chosen per project. For most B2B SaaS, MongoDB + Redis is enough.
How do you deploy to production?
Vercel (serverless functions), AWS ECS/Lambda, Fly.io or our own VPS — depending on project scale. Container-based deploys with Docker are our common path.
